Where do I find the lib file (VS2008) so I can link to the MediaInfo dll ? Its not in the SDK.
You don't need any .lib file: you include the .h, and put the DLL in the same directory as your exe, and the DLL will be dynamically loaded. Look at the example VS2008 project for more details.
For this reason, I don't provide any .lib file. If you absolutely want the .lib, you must build it yourself from MediaInfoLib sources.
